Writing on HuffPo, a physician calls for a mandatory helmet law for all cyclists, motor and otherwise. While I strongly favor helmet use — but oppose making it illegal not to — I’d like to know where he got the unsourced statistic that bike helmets reduce traumatic brain injury (TBI) by 95%.

He also fails to mention that falls are the leading cause of TBIs in the U.S., followed by traffic collisions, hitting or getting hit on the head, and assaults. Or that 45% of injury-related deaths occur in and around the home.

Clearly, the solution is to mandate helmet use for everyone, 24/7.

You know, just in case.

And in another example of America’s obsession with bike helmets, a North Carolina cyclist is killed riding without lights after dark.

Oddly, the reporter focuses on her lack of a helmet, which may or may not have helped, but ignores the obvious risks posed by riding without lights; after all, if she’d been using lights, whether or not she had a helmet might not have mattered.

Meanwhile, the World Anti Doping Agency tells Spain don’t go easy on him or else. And ex-Tour de France champ Floyd “I swear I’m clean and would never, ever dope — oh wait, yeah, I guess I did” Landis says clenbuterol is common in the peloton and guilty riders are protected. Is it just me, or is Contador’s “clear me or I quit” attitude actually starting to make Floyd Landis look good? Or like less of a pathetic lying jerk, at least?

Or maybe not the only one, anyway.

In other pro news, politics may play a role in the investigation into Lance Armstrong, and rising star Taylor Phinney may focus on the road classics rather than track events, and may defend his world pursuit crown
